Title: Belt for transferring component and chip component feeder using the same
Inventor: ITO TATSUICHI
IPC: H05K13/02
Filed: 1998-01-28
Abstract: PROBLEM TO BE SOLVED: To provide a belt for transferring component capable of satisfactorily transferring a chip component, by avoiding that the chip components under transferring contact each other. SOLUTION: A continuous oxbow groove 8a having its width and depth slightly larger than the width and depth of a chip component P is formed in the center of the surface of a belt 8 in a lengthwise direction. Since the chip component P can be transferred with its lateral position kept by the groove 8a, the contact of the chip component with other component is securely avoided and a satisfactory component transferring is secured.

Abstract: PURPOSE:To shorten a running time and to improve the frequency characteristics, which are limited by the running time, by making the conductivity type of a light absorbing layer to be a p-type, and using electrons as the minority carriers for the light absorbing layer. CONSTITUTION:A p<->-InP buffer layer 2, a p<->-InGaAs light absorbing layer 3 and a p<->-InP window layer 4 are continuously grown by a vapor growth method, a metal-organic-pyrolysis vapor-growth method or a molecular epitaxy method using a p-type InP substrate 1. An n<+>-InP layer 5 is formed by implanting Si ions so that a junction front is located at an interface between the InP window layer and the InGaAs light absorbing layer. The diameter of the p-n junction is set at 30mumphi in order to reduce a junction capacitance. As passivation films 6, double films of SiN and SiO2 are used. A reflection preventing film of SiN 7 is provided at a light receiving surface so that external reflection is suprressed to less than 1%. Well known ohmic electrode material is used for an n-type ohmic electrode 8 and a p-type ohmic electrode 9. The saturation speed of electrons in InGaAs is twice the saturation speed of holes. Therefore, a cutoff frequency limited by a running time is improved twice that in a conventional photodetector.

Title: Split type culvert
Inventor: WATANABE KEIICHI
IPC: E03F3/04
Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To provide a split type culvert which can distribute stress concentrated to joint surfaces of split parts. SOLUTION: In a split type culvert 1, horizontal split surfaces (joint surfaces) 2 of split parts are vertically shifted from each other so that the split surfaces 2 are defined in two horizontal planes at least at two positions. By shifting the positions of the two split surfaces 2 which are a weak point of the split type culvert 1, the split surfaces 2 are prevented from being positioned in one and the same horizontal plane, thereby it is possible to prevent stress from being concentrated to the joint surfaces, which woud occur if the joint surfaces are located in one and the same horizontal plane. Further, since the split surfaces 2 are shifted from each other, the positioning of the upper and lower culverts 1a, 1b during assembly thereof can be easily made, and lateral shifting of the split type culvert 1 which would occure upon occurrence of an earthquake or the like can be prevented.

Title: Cmos transistor
Inventor: UEDA TOSHIAKI
IPC: H01L27/092
Filed: 1989-01-25
Abstract: PURPOSE:To make a chip area small and obtain a transistor which is stable to outside noise by forming isolation regions in such a way that the regions are adjacent to wells. CONSTITUTION:A CMOS transistor is equipped with: an opposite conductivity type epitaxial layer 2 which is formed at one surface of one conductivity type semiconductor substrate 1; the conductivity type isolation regions 3 which demarcate an element formation region by penetrating from the surface of the epitaxial layer 2 into the semiconductor substrate 1; and a one conductivity type well 4 which is formed in the foregoing element formation region. In the above transistor, one of the above isolation regions 3 is allowed to be adjacent to the above mentioned well 4. In this way, for example, the formation of each p<+> type isolation region which is adjacent to a p-type well reduces an area occupied by a chip and miniaturizes the CMOS transistor. Further, for example, overlapping between the highly concentrated well contact layer of the p<+> type isolation region and the p-type well which is achieved by causing the above two regions to be in contact makes well potential stable and improves a resistance to noise.

Title: Substrate processing method
Inventor: YASUDA MUNEHIRO
IPC: H01L21/68
Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To provide a substrate processing method which comprises a load-lock container and can shorten a substrate processing time in a substrate processing apparatus. SOLUTION: When transportation of a wafer W to a load-lock container 32 is terminated a controller 48 first executes its control operation to set the load-lock container 32 and a processing container 1 in their vacuum state. This causes a vacuum pump 39 to be driven, thus opening air valves 40 and 41. As a result, the load-lock container 32 and processing container 31 are set in their vacuum state. Next the controller 48 executes its control operation to transfer the wafer W to the processing container 31. This causes a furnace port gate valve 33 to be opened, thus moving a board elevator 35 upwards. The controller 48 then executes its control operation to form a thin film. This causes a reaction gas to be supplied to the processing container 31. As a result, a predetermined thin film is formed on the wafer W.

Abstract: PURPOSE:To rapidly change over automatic and manual feed of a slider by providing a feed slider apart from slider and connecting and separating both. CONSTITUTION:When a connecting switch 37 is on, an elevator 17 is actuated by a command signal S4 and the slider 3 and the feed slider 20 are connected. Then, a motor 7 is driven by a joy stick 52 and the slider 3 can be fed automatically. When a connection means 12 is released, since the slider 3 is via air bearings 9 and 10, the high-speed manual feed can be attained by the little force. In order to change over the manual feed to the automatic feed, when the sliders 3 and 20 are transferred properly and an interval is made (l), the means 12 can be in a connecting state immediately. On this occasion, output signals S1 and S2 of a sensor 31 for measurement and a sensor 32 for feed are compared and an approaching state with respect to the interval (l) is displayed 34. When the interval (l) is attained, since a lamp 36 turns on and off, the operational time of the switch 37 can be easily grasped. In this way, feed work capable of the high-speed measurement can be performed.

Abstract: PURPOSE:To project characters on a view finder even during recording, by controlling a value of a termination resistor of a video signal with a character signal, decreasing the value, changing a load of a video signal output of a camera and superimposing the character signal on the video signal. CONSTITUTION:A character signal (a) from a character signal generator 9 is applied to a summing circuit 8 and a termination resistor variable circuit 13. The signal (a) is applied to a base of a transistor (TR) Q via a resistor R2 of the circuit 13, the TR Q is saturated and a resistor R1 is grounded. Thus, while the signal (a) exists, the resistor R1 is connected in parallel with a termination resistor R0, resulting in reducing the resistance. As a result, the level of the character signal component only is remarkably reduced in the video signal at a video input terminal 4. The character signal is projected in black in the view finder 6 at recording.
